IMPROVEMENT IN c AR-AXLE BEARINGS Specification forming part of LettersPatent No. 210,475, dated December 3, 1878 application filed July 16,1878.

To all whom it may concern:

Be it known that I, AsA E. STRATTON, J r., of Brazoria, in the county ofBrazoria and State of Texas, have invented a new and Improved Axle-Box,of which the following is a specification Figure 1 is a plan view of myimproved axle-box. Fig. 2 is a longitudinal section, taken on line a: min Fig. 1. Fig. 3 is a transverse section, taken on line 3/ y, Fig. 2.

Similar letters of reference indicate corre sponding parts.

My invention relates to journal-boxes, and is more particularly designedfor car-axles.

It consists-in a box having a chambered back for containing oil, andhaving'grooves along the straight edges of its bearing-surface forreceiving a wick, the ends of which extend through holes in the box intothe oilreservoir.

The object of my invention is to provide a journal-box which willcontinuously lubricate itself, and thereby avoid heating and cutting.

Referring to the drawings, A is a box or brass, made ot'any of thematerials comm only used for the purpose, and having in its upper orplane side two oil-cavities, a, which are separated by a partitionyb,which forms a support for the middle of the bearing-surface c.

semicircular grooves (Z are formed in the box along the lower edges ofthe bearing-surface to receive the wicks e, which extend through holesin the box into the cavities a for conveying oil to the hearing.

In the bearing-surface 0 there are several cavities, f, for containingsurplus oil and receivin g any particles that may be cut from thejournal or bearing.

The ends of the box are recessed to afford room on the journal betweenthe box and the side of the casing for gum and dirt that may be forcedfrom the bearing-surfaces.

The box is fitted to the ordinary axle-box housings, and two oil-holesare made in the top of the housing for the purpose of feeding theoil-cavities a.

The wick e not only supplies the journal with oil, but it also removesany dust or grit
